Messatoporus kerzhneri Kasparyan & Ruíz 2008

( Fig. 333 )

* Messatoporus kerzhneri Kasparyan & Ruíz 2008: 325–327 . Description, keyed. Holotype ♀ (UATM, pictures examined). Type data: México, Veracruz, Estación Los Tuxtlas , 20 m, bosque tropical, 17.IX.1989, IMKerzhner.

Female. Fore wing 11.00 mm long. HEAD: Antenna with 23 flagellomeres; flagellum strongly flattened and compressed on apical 0.3; apex of apical flagellomere about as wide as base, not distinctly tapered.

THORAX: Mesoscutum shiny and almost impunctate, apparently strongly and uniformly convex. Mesopleuron sparsely pilose; epicnemial carina complete, reaching subalar ridge, distinctly sinuous; Metapleuron moderately punctate, without transverse wrinkles.

PROPODEUM: Propodeal wrinkles distinct posteriorly to anterior transverse carina.

WINGS: Fore wing vein 1-Rs+M very weakly sinuous, with bulla placed around its midlength; crossvein 1mcu irregular, limit between 1m-cu and 1-Rs+M more or less traceable; vein 1M+Rs anteriorly straight, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by about 0.7 of its own length; vein 2Cua distinctly shorter than crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs small, pentagonal, about as wide as high; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, about the same length; vein 3-M about as long as 2- M; 4-Rs distinctly sinuous; 4-M slightly curved backwards. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs reaching wing margin; crossvein Cua slightly longer than cu-a; vein Cub distinctly convex on posterior half, forming somewhat acute angle with vein Cua.

METASOMA: First tergite moderately long. OST 1.70; ovipositor moderately stout, straight.

Color. Head, meso- and mesosoma black and yellow, with orange marks. Head: black; clypeus, mandible except apex, mouthparts, malar space, supraclypeal area, scape ventrally and complete orbital band, pale yellow (241,236,177); f6–11 entirely white, f5 and f12 partially white. Mesosoma: black; pronotal collar, dorsal margin of pronotum, propleuron, [subcircular spot on mesoscutum not visible, possibly hidden by pin hole] scutellum except posterior margin, tegula, subalar ridge connected to central mark that covers most of mesopleuron, mesosternum, dorsal division of metapleuron, almost all metapleuron, and arc-shaped, medially narrower mark on propodeum, pale yellow; fore and mid coxa pale yellow, mesal face with brownish to blackish marks; fore and mid trochanters and femora pale yellow, with blackish posterior stripes; fore and mid tibiae and tarsi pale yellow, t5 dorsally brownish; hind coxa anteriorly orange, posteriorly pale yellow, with blackish marks between orange and yellow areas on basal 0.5; hind trochanters marked with blackish and brown; hind femur brownish, basal 0.8 of ventral face and apical 0.2 blackish; hind tibia and tarsus entirely yellow lighter towards apex. Metasoma: black; T1 dorsally pale yellow at anterior 0.7; T1–6 with progressively longer posterior pale yellow stripes, medially indistinct at T7–8;, S1–6 pale yellow, S2–3 with anterior brownish mark.

Male. Unknown.

Comments. More similar to M. arcuatus , M. grandis and M. covarrubiasi , all these species sharing features like the generally large size, hind tibia uniformly yellow, hind trochanters posteriorly blackish, fore and mid femora posteriorly blackish and hind femur mostly blackish. It can be distinguished from those species in having hind coxa orange and yellowish, with a dorsal black mark. Other noteworthy features are the central mark on mesopleuron connected to the yellow subalar ridge and the long ovipositor, OST 1.70. The female holotype is the only known specimen.

Biology. Unknown.

Material examined. Pictures of the holotype. Pinned. Head and prothorax partially detached from remainder of thorax; fore femora, tibiae and tarsi missing; right mid leg after first trochanter broken and glued to the pin; left tarsus missing.

Distribution. Recorded only from the type locality, in southeastern Mexico ( Fig. 333 ).
